RAILWAY-SWITCH LOCK. i

Application filed October 11, 1923, Serial No. 667,882.

To all whom t may concern:

Beit known that I, JOSEPH R. DooLnY, a citizen of the United States,residing at Mobile, in the county of Mobile and State of Alabama, haveinvented certain new and useful Improvements in Railway-Switch Locks, ofwhich the following is a speciication.

This invention relates to certain new and useful improvements inkrailway switch locks, and it has for its objects among others toprovidea simple and reliable locking vmeans for a railway switch thatwill lock the switch in a predetermined position, so as to eliminate allpossibility of the train splitting the switch.

The present invention has for a further object to provide a simple,efcient and easily operated mechanism that can be applied to theshifting mechanism as at present used by all railroads without materialchange therein. The present invention comprises few parts and thosereadily assembled and not liable to get outl of order or to be damagedin any way in use.

Other object-sand advantages of the invention will hereinafter appear,and the novel features thereof will `be specifically defined by theappended claims. f.

The invention, in `its preferred form, is clearly illustrated in theaccompanying drawings, which, with the numerals of reference markedthereon, form a part of this specification, and inwhichj .Figure lis atop plan showing the application of my present invention. i

Figure 2 is a vertical cross section, as on the line 2-2 of Figure 1,looking in the directiony of the arrows.

Figure 3 is a bottomplan of parts as shown in Figure 1.

-Figure 4t is a vertical cross section as on the line 4 4 of Figure 1,looking in the direction of the arrows.

Figure 5 is an enlarged perspective de-y tail, `with the rail invertical section and a portion broken away.

Figure 6 is a view of the yoke bar. Figure 7 shows in perspective therocker member and the parts associated therewith. Like numerals ofreference indicate like parts throughout the several views.

vrocking member, soon to be described, be-

Referring to the drawings- 1 designates the ties, 2 the rails and 3 thei switch, of usual construction.l

The switch rails 3 are connected at a distance from their points by atransverse bar 4;, the ends of which are pivotally connected as at; 5with the brackets, lugs or the like 6 which are secured to the adjacentfaces of the said switch rails in any suitable manner.

The switch rails are joined adjacent their points by they transversebar`7 which constitutes the shifting bar, but this bar is not rigidlyconnected to the switch rails but is provided near each end with anelongated s lot 8, in which slots work the bolts or the like 9 which arecarried by and project downward from the brackets or lugs or the like 10secured to Athe adjacent faces of the switch rails as seen best inFigure 4L. This shiftingbar 7 is mounted to slide within predeterminedlimits and one end is ex-v` tended as seen at 11 and is pivotallyconnected at one end as at 12 with one end of the arm 13, the other endof which is connected withy the pivot of the throw arm 14 the `pivot 15of which is supported in the bearing 16 on the tie or other support 17,all as clearly seen in Figure/1. It will be seen that this connectionbetween the switch rails and the bar 7 is such that the said shiftingbar moves some little distance before the gins to move.

18 is a yoke bar, preferably'of steel7 having its ends turned up as seenat 19, each of the said turned-up portions being peculiarly shaped, asseen, for instance, in Figure 5, oo having a notch or the like 2O toengage the base 21 of the rail 2, anda second notch or recess 22 forcooperation with a wedge member 23 which is designed for cooperationwith an oppositely disposed wedge member o5 24 which is adapted to bearagainst the web `25 of the rail'2 as seen in Figure 5. These two wedgemembers are constructed to be moved relatively to each other by means ofa screw 26 and a nut 26a thereon, as will be 100 readily understood fromFigure 5. By this means isnot only the yoke bar held secure ly in place,but the said meansprovides for adjustment so as to keep the pivot of therocking member, soon to be described, centrally between the rails andhold the rails to proper gauge. This also serves to prevent spreading ofthe rails at this point and aids all the parts iii-withstandingthestrain incident to the operation oi the switch rails.

At the centre of its length the yoke bar is provided, either integral,or' made sepa.- rate and ailiXed thereto in any 'suitable way with amember 27 which is in the 'rorm of an inverted box-like compartment, seeligureV l, which carries the pivot 28 i'or the rocking` member 29 to thefree ends ot the two arms 30 and 3l of whichV are pivotally connected asat; 32 thelocking bars 33 and 34 as seen clearly in Figure 4. The 'freeend of each locking bar is turned upward as seen in F igures 2 and 4 at35, and at theangle each is provided with an elongated slot 36, througheach of which slots extends a horizontal bolt or the like 87 carried bythe yokev bar 18. The upperv 'ends of these upward extensions 88 areformed to engage the webs of the switch rails as seen in Figure 2;

Secured to the under side of the shitting bar 7 is a bracket 39 whichdepends therefrom, being provided with an elongated vertical slot 40,the bracket being danged as at 41 and the securing bolts passing throughthe top flange as seen clearly in Figure 3. The rocking member isprovided with an open-ended slot 42 in which is received the block 48,44 being a bolt which passes through the slot 40 in the bracket 39 andthrough the slot 4.2, and through the said block and receivingthe nuts45 on opposite sides of the bracket 39.

The'block is prOvidedwith the hole '46 for the reception of the bolt 44,and opposite sides oiB this block are formed with the vertical channels47 and 48, as seen in Figure 7, between the flanges 49 or" which arereceived the lugs 50 which depend from the rocker member 29'uponopposite sides of the slot 42 therein, all as will be clearly understoodfrom Figure 7;

By moving the bolt 44 upward in the elongated slot 40 in the bracket 39the move- Vment of the locking bar is shortened, and by moving the saidbolt toward the bottoml end of the said elongated slot the movement ofthe locking bar is increased, thereby adding to its locking ability.

As seen best in Figure G the member 27 Von the yoke bar 18 is providedwith the depending lug 1Sa having the hole 18" for 'the reception of thepivot 28, The opposite edges 51 and 52 of the member 27 form stops forcooperation with the adjacent ends 53 and: 54 of the members 33 and 34as seen clearly in Figure 1.

The various parts above described'may be made of any material suited tothe purpose, and it will be evident that the proportions and relativearrangement of parts may be varied within certa-in limits withoutdeparting from the spirit oztl theinvention or sacrilicing any ot itsadvantages.

lfie locking device maf be used upon either' side oif the shifting barwithout any change in any of the parts or their relative arrangement. Y

The operation will be readily understood from the iioregoing descriptionwhen taken in connection with the annexed drawings. Brieiy stated, it isas ollowsg-with the parts as shown in Figure 2 the left hand switcllrail is thrown hard against the adjacent rail 2, the locking bar 33 isstraight and horizontal ai its portion 38 is Vforced hard againsty theswitchrail 3, the otherlocking bar 34' being downwardly inclined, its

tace 54 having been moved out of Contactl with the shoiiider or edge 52of the member 18 and the upstanding end 38 of the right hand end o thesaid locking bar 34 out oli contact with'the adjacent switchrail 3.

When the lever 14 is moved into the opposite position the locking bar 33is moved by reason of the rockingV ofthe member 29so that the parts willbe placed in the reverse oosition the lookin0` bar 34 bein nlaced 7 n gl horizontally and the locking bar caused" to assume the downwardlyinclined position, with the result that the opposite switch rail isforced against the adjacent rail 2 and locked in such position.

i' djustment of the bolt 44 up or down as above desc 1ibed provides forthe necessary adjustment of the throw of the locking bars. The provisionof the elongated slots 8 in the member 7 in 'which the bolts 9 playpermits of the differential movement required Y to allow the shiftingbar tov move the requisite distance before movement is imparted to therocking member 29. 1 f
